Reconfigurable DSP-FFT design for mobile communication

Abstract

Many Electronic system making use of digital signal processor. Digital signal processing is the application of mathematical operation to digitally represented signals. Signals are represented digitally as a sequence of samples. Often these samples are obtained from physical signal (e.g. audio) through the transducers, A/D converters. After mathematically processing digital signals may be back to physical signals via D/A converters. In some systems the use of DSP is central to the operation of the system. The operation of digital signal processor on input samples could be linear or non linear, depending on the application of interest.
